Block Google DNS on D-Link Routers
Step 1: Start by adding the playmoTV DNS to your router via our router setup guide, but don’t leave the router setup page.
Step 2: In the Setup tab scroll down to the Internet section and write down the IP address, as you have to use it later.
Step 3: Now scroll back up and click the Advanced tab. Once there you’ll find a sidebar on the left. On that sidebar click Routing.
Step 4: Now, for the real deal:
Step 4.1: In the Destination field enter 18.104.22.168
Step 4.2: For the Subnet Mask enter 255.255.255.255
Step 4.3: For the Gateway enter the router IP address (probably 192.168.0.1).
Step 4.4: Select WAN as the Interface and tap the checkbox to enable these settings.
Step 5: Click Save Settings and then click Reboot Later. In most cases this starts working instantly, but if not then reboot your router.
